Good value for industrial use
Solid construction and good pricing for bulk orders. One unit had a minor cosmetic scratch, but it did not affect performance. Will order again.

Durable but heavy
The sleeve is very robust and handles the pneumatic pressure well. It is slightly heavier than expected, but that likely contributes to its stability during operation.

Excellent wear resistance
After two weeks of continuous use in an anchor rod system, there is minimal signs of wear. The bronze alloy holds up much better than the standard steel ones we used previously.

Great replacement part
Needed a quick replacement for a worn-out shaft sleeve. This bronze version arrived quickly and installed without any modification. Highly recommended for mining hardware.

Perfect fit for our drill rigs
We ordered these bronze sleeves for our Model 13 drill rigs in the coal sector. The fit is precise, and the material quality seems excellent for high-friction environments.

Reliable for harsh conditions
Our team uses these in deep shaft operations. The pneumatic compatibility is spot on, and the sleeve maintains integrity under high stress. A reliable component.
Q: What is the exact inner diameter tolerance?
A: The inner diameter is specified at 13mm with a standard industrial tolerance of +/- 0.05mm to ensure a secure fit on anchor rods.
Q: What is the warranty period for this hardware tool?
A: This product comes with a 6-month manufacturer warranty against defects in material and workmanship under normal operating conditions.
Q: Do you offer bulk discounts for mining companies?
A: Yes, we offer tiered pricing for bulk orders exceeding 50 units. Please contact our sales department directly through the 'Contact Seller' button for a custom quote.
Q: Is this sleeve compatible with non-pneumatic drill rigs?
A: This specific model is designed primarily for pneumatic accessories. While it may fit mechanically on some non-pneumatic rigs, we recommend checking your equipment specifications for pressure ratings before installation.
Q: How does bronze compare to steel for this application?
A: Bronze offers superior corrosion resistance and lower friction coefficients compared to standard steel, making it ideal for the dusty and potentially humid conditions found in coal mines.
